How to solve identities of trigonometry cos tan=sin?




Sagot :

cos tan=sin tan=sin/cos therefore: cos sin/cos=sin then cancel the cos so that sin=sin
cos=cos
sin=sin
tan=[tex]\frac{sin}{cos}[/tex]

The equation is:
cos tan=sin
Since there are no operations in the middle, we can classify it as multiplication. Now, tan is sin over cos, so substitute:

[tex]cos(\frac{sin}{cos})=sin[/tex]

Since you will multiply the cos to tan, the cos will be canceled.
sin=sin

Hope this helps =)
